To aZZ whom it may concern.-

Be it known that I, WILLIAM M. CLARK, a citizen of the United States,residing at Philadelphia, county of Philadelphia, and State ofPennsylvania, have invented certain Improvements in Printing-Presses, ofwhich the following is a specification.

This invention is more particularly designed to provide improvedmechanism particularly adapted for job-printing, in which are combinedthe cylinder-printing principle with the convenient job-press design. Itprovides a press which is simple and strong in construction, rapid andeasy of action, capable of being produced at a small price, and welladapted not only for the class of work done by all job-presses, but alsofor half-tone work, em-

bossing, and the finer grades of printing not usually capable of beingproduced upon the job-press. It is also designed for web-feeding,automatically cutting and delivering the printed sheets, and for theoperation of numbering and counting mechanism.

The nature and characteristic features of the improvements will morefully appear by reference to the following description and theaccompanying drawings in illustration thereof, of which Figure 1represents a side elevation of a printing-press embodying the invention.Fig. 2 represents a rear elevation of the press. Fig. 3 represents asectional view taken on the line 3 3 of Fig. 2. Fig. 4 represents asectional view taken on the line 4 4 of Fig. 1. Fig. 5 represents asectional view taken on the line 5 5 of Fig. 1. Fig. 6 represents asectional view taken on the line 6 6 of Fig. 3. Fig. 7 represents asectional view taken on the line 7 7 of Fig. 3. Fig. 8 represents a sideelevation of the feeding and cutting mechanism opposite to that shown inFig. 1. Fig. 9 represents a top plan view of the feeding and cuttingmechanism. Fig. 10 represents a sectional view taken on the line 10 10of Fig. 9. Fig. 11 represents a sectional view taken on the line 11 11of Fig. 9, and Fig. 12 represents an end elevation of the feeding andcutting mechanism.

As shown in the drawings, the frame 1 has journaled therein the shaft 2,which has fixed thereon the driving-wheel 3 and the pinions 4. Thesepinions engage and drive the spurwheels 5, fixed on the spindles 6,which are journaled in the frame and have fixed thereon the cams 7.Riding on these cams are the rollers 8, which revolve on the journals 9,ec-

centrically fixed by the disks 9 to a shaft 10, journaled in theframe-shoes 11 and rocked by the lever 12, the shoes having the pivotalconnections 13 with the frame and being rocked thereon by the cams 7through an arc variable by changing the position of the rollers 8,carried by the movable journals 9.

A pressure-segment or cylindrical platen 14 has the radial arms 15,which carry a rod 16, having rollers 17 thereon adapted to pivot and runin the guides or ways 18 of the shoes, the rod being connected by thelinks 19 with the crank-pins 20 of the spur-wheels 5, by which theplaten is rocked. The rocking movement of the platen is controlled bythe links 21,

having the pivotal connections 22 with the platen and the pivotalconnections 23 with the frame. The links 21 have the pivotal connections27 with the links 25, and the latter have the pivotal connections 26with the arms 29, pivot-ally supported in the frame by the rod 28. Thearms 29 carry the ink-roller 30, adapted to oscillate in contact with atypeform 31, held by the chase 32 upon a bed 33, the bed being connectedwith the support 34 by the screw 35.

Rocking with the rod 28 is a finger or projection 36, adapted to engagea lever 37, having the fulcrum 38 and carrying a gravitypawl 39, thelatter being adapted to engage a circular rack 40 on the'under side ofthe inkdistributing disk 41, which has the journal 42 bearing in thesupporting member 43.

Journaled on the frame is a paper-roll 44, from which the paper 45 isdrawn over the rollers 46 and 50 between the type-form and the platen. sThe paper is carried thence over the table 49, through the guides 51,between the rollers 52 and 53, and beneath the presserarm 54 and theknife 55.

The roller 53 has the ratchet-wheel 56 fixed thereon and actuated by aknife-pawl 57, fixed in relation to a pinion 58, adapted to rock uponthe shaft 59, which carries the roller. The pinion is rocked by theengagement therewith of the segmental spur 60, journaled on the spindle61 and rocked by the link 62, connected with the crank-pin 63 on thesegmental spur. The link 62 is journaled on a crankpin 64, fixed on agraduated slide 65, having the slot 66, through which a set-screw 67passes, being fixed eccentrically in relation to the axis of a cam 7, bywhich the length of feed is regulated. The other cam 7 has eccentricallyfixed in relation thereto a boss 71, which is adapted to engage and rocka lever 72, having the fulcrum 73. This lever has the pivotal connection74. with a link 75, which has the pivotal connection 76 with the knife55, the latter having the fulcrum 77 and being elevated by the spring78. The presserarm 54 has the fulcrum 79 and is held elevated by thespring 78, being depressed by the spring 80 to engage and hold the paperwhen the depression of the knife effects the depression of the spring78.

It will now be understood that the revolution of the driving-shaft 2effects, through the gears 4 and 5, the revolution of the shaft 6 andcams 7 and the reciprocation of the links 19, by which the guiding-shoes11 and the platen 14 are reciprocated, the cams acting, through therollers 8, to elevate the shoes, so that the guides 18 and the links 21cause the platen to roll upon its bed or type-form in the printingmovement and to drop the shoes, so that the guides cause the platen tobe withdrawn from the bed on the return movement. As the ink-roller 30is connected with the links 21 by the links 25 and arms 29, it willreciprocate on the type-form 31 in unison with the action of the platen.By moving the lever 12 and revolving the journal of theeccentrically-mounted rollers 8 the rise of the shoes may be limited, sothat the platen will not be thrown in contact, but will reciprocate outof contact with the type-form.

Simultaneously with the reciprocation of the platen the cams 7 eflectthe intermittent feeding and cutting operations in alternation, thepaper being advanced as the platen returns and the cutting beingeffected simultaneously with the printing movement. The feedingoperation is effected by the reciprocation of the link 62, segmentalgear 60, spurgear 58, and pawl 57, rotating the roller 52, by which thepaper is advanced. The cutting operation is effected by the depressionof the lever 72, the link 75, and knife 55 against the action of thespring 78, the holding device 54f being depressed by the spring 80 tohold the paper as the knife descends.

By referring to Figs. 1 and 3 of the drawings it will be seen that theupper part of the curved face of the platen during its downward orreturn movement gradually approaches a horizontal position, whereby topermit a ready feeding and removal of the sheets to be printed. Thusthis design of press has all the feeding advantages of the ordinaryflatbed and platen presses, and at the same time it has the furtherimpression advantages of the cylinder-press, the latter being due to thecurved platen.
